I am begginer at JS and I want to change the innerText of HTML element.

This works:

let span = document.querySelector('span');

span.innerText = 20;

<span></span>

And this does not work:

let span = document.querySelector('span');

let element = span.innerText;

element = 20;

<span></span>

Why is that happening?

You're just copying the text to the variable. The variable is not an alias for the `span.innerText` expression. – Barmar Jul 09 '21 at 15:41
@dmikester1 He already knows how to do that, he did it in the first snippet. – Barmar Jul 09 '21 at 15:41
It's the same reason that `a=1; b=a; b=2;` doesn't change `a`. – Barmar Jul 09 '21 at 15:43
